Open Source projects

All open source projects are available on our AppSignal GitHub organization.

Our main projects include:

Other projects we have open sourced, and are used internally by other projects, include:

  • AppSignal Rust agent Early stage proof of concept of AppSignal Rust integration.
  • sql_lexer Rust library to lex and sanitize SQL queries.
  • Rust library to read out system stats from a machine running Linux.
  • public_config Parts of configuration that are public, such as magic dashboards.

Using git and GitHub

We organize most of our git repositories on GitHub using a main and develop branch. The main branch corresponds to the current stable release of a project. The develop branch is used for development of features that will end up in the next minor release of a project.

Feature branches are used to submit bug fixes and new features using GitHub Pull Requests. When submitting a Pull Request the changes are tested against a variety of Ruby/Elixir versions and dependencies on Travis CI. The submitted change is also reviewed by two or more AppSignal project members before it is accepted.


AppSignal is very open about changes to its product. Changes to integrations and the application itself are all visible on Big updates will also be posted on our blog.

All AppSignal integration projects use Semantic Versioning for versioning of releases. Documentation and other non-version specific projects do not use explicit versioning, but will mention related version specific content, such as in which version a feature was introduced.

Every stable and unstable release is tagged in git with a version tag and can be found on every project's GitHub page under "Releases".
